|---|---|---|---|
| CVE-2026-75889 | Aug 27, 2026 |
Grafana Alloys ServiceMonitor bearerTokenFile LFDGrafana Alloys prometheus.operator.servicemonitors component allows a user who can create or modify ServiceMonitor resources in a watched namespace to specify an arbitrary local file through bearerTokenFile. Alloy reads the file and sends its contents as a bearer token to an attacker-controlled scrape endpoint. This may disclose files accessible to the Alloy process, including its projected Kubernetes service account token, potentially granting the attacker Alloys Kubernetes permissions. Exploitation requires ServiceMonitor write access and lower privileges than Alloys service account. |

| CVE-2026-19854 | Aug 27, 2026 |
Grafana ClickHouse Plugin TLS Bypass via PDC/secure SOCKSWhen the ClickHouse plugin uses Native protocol (the default) with PDC or secure SOCKS, it asks for TLS but the connection library ignores that and talks to ClickHouse in the clear. Username, password, queries, and results can be read on the hop after the proxy. The server certificate is never checked, and a configured client certificate is not sent. |
|
| CVE-2026-19197 | Aug 26, 2026 |
Grafana: Insecure Deletion of CrossOrg Dashboard Snapshots (CVE202619197)A user with organization administrator permissions can delete dashboard snapshots belonging to other organizations on the same Grafana instance, and can recover a snapshot's secret delete key using only its public share key (broken access control). |
|
| CVE-2026-17033 | Aug 24, 2026 |
Grafana XSS via alert.generatorURL in external Alertmanager alertsAn authenticated attacker with Editor access or alert.instances.external:write can submit an external Alertmanager alert containing a controlled generatorURL. The attacker is authorized to create the alert, but not to execute script in another user's Grafana session. Grafana renders alert.generatorURL directly as the Alert Details See source LinkButton href without URL-scheme sanitization or a safe-protocol allowlist. The click interceptor's :// heuristic can be bypassed by placing :// inside a JavaScript comment. When a user with read access clicks See source, the browser executes attacker-controlled JavaScript in the Grafana origin with the clicking user's permissions. |
|
| CVE-2026-17183 | Aug 19, 2026 |
Grafana Alert Rule Query Auth Bypass via SSRAn authenticated user with permission to create or edit alert rules can bypass datasource query authorization by marking an alert rule query as a server-side expression while referencing a real datasource UID (incorrect authorization). This can expose data accessible through Grafana's configured datasource credentials to users who lack permission to query that datasource. |
|
| CVE-2026-11817 | Aug 17, 2026 |
Grafana Cross-Org Info Disclosure via /api/access-controlThis vulnerability only affects Grafana stacks configured with multiple organizations; single-organization deployments are not impacted. In a multi-organization stack, a user who is an Org Admin of a single organization can call GET /api/access-control/users/permissions/search?actionPrefix=dashboards: and receive permission data belonging to other organizations. The disclosed data is limited to dashboard and folder identifiers (UIDs) and per-user permission/scope mappings (which user holds which access on which dashboard). Dashboard contents, panels, query results, datasource credentials, secrets, and personal data are not exposed. This is a limited cross-organization information disclosure affecting multi-org deployments only. |
|
| CVE-2026-19516 | Aug 11, 2026 |
SSR In Grafana mcp-grafana via X-Grafana-URL HeaderA caller-supplied X-Grafana-URL request header controls the destination of mcp-grafana's outbound requests, and the grafana_api_request tool lets the caller also choose the HTTP method, path, and body. Because the destination is not restricted to the configured Grafana instance, a caller can direct requests at internal, loopback, and link-local network services (including metadata endpoints) and read the responses, resulting in server-side request forgery. The fix for CVE-2026-15583 prevented the configured service-account token from being sent to unintended destinations but did not restrict the destinations themselves. |

| CVE-2025-41118 | Apr 15, 2026 |
Pyroscope API Secret Key Leak via Tencent COS Backend <1.15.2/1.16.1/1.17.0Pyroscope is an open-source continuous profiling database. The database supports various storage backends, including Tencent Cloud Object Storage (COS). If the database is configured to use Tencent COS as the storage backend, an attacker could extract the secret_key configuration value from the Pyroscope API. To exploit this vulnerability, an attacker needs direct access to the Pyroscope API. We highly recommend limiting the public internet exposure of all our databases, such that they are only accessible by trusted users or internal systems. This vulnerability is fixed in versions: 1.15.x: 1.15.2 and above. 1.16.x: 1.16.1 and above. 1.17.x: 1.17.0 and above (i.e. all versions). Thanks to Théo Cusnir for reporting this vulnerability to us via our bug bounty program. |

| CVE-2026-21725 | Feb 25, 2026 |
Grafana TOCTOU Data Source Deletion ReuseA time-of-create-to-time-of-use (TOCTOU) vulnerability lets recently deleted-then-recreated data sources be re-deleted without permission to do so. This requires several very stringent conditions to be met: - The attacker must have admin access to the specific datasource prior to its first deletion. - Upon deletion, all steps within the attack must happen within the next 30 seconds and on the same pod of Grafana. - The attacker must delete the datasource, then someone must recreate it. - The new datasource must not have the attacker as an admin. - The new datasource must have the same UID as the prior datasource. These are randomised by default. - The datasource can now be re-deleted by the attacker. - Once 30 seconds are up, the attack is spent and cannot be repeated. - No datasource with any other UID can be attacked. |
